To the swivel-arm nearest of its operative position; Fig. 7, an isometric the so-called builder-cam V 1s connected one end of a chaino which runs overachain-pulley or grooved idle-roll o and, at the other end is secured to the upper end of a curved rack 11 which is adj ustably connected to the builder-arm v said arm '0 having a hub, turning on a stud '0 projecting from the frame of the machine, and an anti-friction roll 21 being journaled in said arm '0 below the builder-cam V and being held against said builder-cam, by a weight f adj ustably supported on the weight-lever or weight-arm f of the cross-shaft, the effect of which weight f is to tighten the chain 7) and raise the builder-arm '0 and the cross-shaft arm f, the downward motion of both said arms being caused by the pressure of said builder-cam V upon said roll 0 The rack v is engaged by a worm 22 (indicated by a dotted circle in Fig. 15,) fast on the worm shaft 12 journaled in the builder-arm v and the ratchet o is also fast on said worm-shaft '0 and is engaged by a pawl r pivoted on the weighted pawl-arm 11 and having an arm o which is struck by a dagger v secured on the frame of the machine, when the builder-arm is raised gradually, to shorten the traverse of the ring-rail by carrying the lower end of the chain '0 nearer to the center of motion of the builderarm.

The parts which operate the builder-arm and cross-shaft arm are all of the usual construction and operation. It will be seen that the ring-rail is raised by the falling of the weightf and falls by its own gravityand the gravity of its connected parts.

The separators I are of sheet-metal and are secured by screws 2' to the separator-bar J which is arranged back of the ring-rail, parallel therewith, and has secured to it as many brackets K as there are separator-rods N.

Each bracket K is provided with two laterally-projecting pins 10 parallel with each other and with the axis .of the bar J. The pin 70 enters a slot Z in the top of the socket L and serves as a pivot on which the bar J may be turned to raise the separators I out from between the spindles or to restore said separators to operative position, the lower end of said slot being rounded to fit the pivot-pin k. The socket L has in front of the slot Z a projection Z, curved concentrically with the rounded lower end of the slot Z, the distance between the lower end of said slot and the curved surface of said projection being equal to the space between the pins 7a 70 When the separators are turned down into the position shown in Figs. 2 and 5, the pin 70 rests in a depression Z on the front of the socket-piece at the lower end of said projection Z.

The foregoing description applies equally to the improvement in yarn-separators for spinning-frames, described in United States Patent, No. 476,731, granted June 7, 1892, to me, but the slot Z in this application is vertical on the front side, except that it is cut under at the bottom,at Z", to fit the pin it, whereas in said patent the corresponding slot has straight parallel backwardly-inclined front and rear sides. The reason for making the principal part of the slot 1 vertical in this application is to enable the separatorbar and the separators to be lifted vertically, drawing the pivot-pins is out of the sockets L, when it is desired to remove said bar or separators for any purpose, without striking a rollerbeam, in spinning-frames where the rollerbeam extends so far forward as to be struck by the separators if said slotsZ were backwardly-inclined. Each socket-piece is provided with an upwardly-projecting stop 1 substantially as in said patent, except that instead of the separator-bar J striking said stop when the separators are turned up from between the spindles, the bracket K, shown and described in this application is provided with a lateral projection 70 which striking against said stop Z prevents the farther backward movement of the separators. The separator-bar, when in its normal position, is prevented from being disengaged from the socket-piece by the projection Z and pin k holding the pivot-pin k in the lower portion Z of the slot Z, but when the separators are lifted the pins 70' k are in the position shown in Fig. 6, and allow the pivot-pin 7a to bem'oved back sufficiently to rise in the slot l. The projection 70 is arranged between the separator-bar K and the pivot-pin k and is below the top of said separator-bar, as shown in Fig. 5, and therefore allows of the back of the stop being placed as far forward as the back of the socket L, and therefore allows the socket to be arranged at aless horizontal distance from the roller-beam than it was possible to place the corresponding stops and socket in the device shown in said patent. As in said patent the socket-piece L has a collar Z held on the upper end of a vertical separator-rod N by a set-screw Z turning in said collar and thrusting against said rod, there being as many separator-rods as there are lifting-rods, each separator-rod slidingin the sleeves m m of a stand M secured to the guide-rail E by bolts m (see Fig. 1) and being raised by the rising of a cross-shaft arm f, the stud f supporting an anti friction roll f precisely like the roll f above referred to but arranged on the opposite side. of said arm f, each separator-rod beingprovided with a foot 0 (see Figs. 1, 2 and 8), the

lower end of which rests on the anti-friction roll f during the traverse of said separatorrod. Said stand M and foot 0 differ however from the corresponding parts shown in said patent, as will hereinafter more fully appear.

The stand M between the sleeves m m is provided with a vertical slot m to receive a projection 19' on an adjustable collarP which surrounds the separator-rod N and is held at any desired distance above the foot of said separator-rod by a set-screw p which thrusts against said separator-rod, said collar Plimiting the downward movement of the separator by striking on the top of the lower sleeve mon the stand M, and its projection 19' laterally filling the slot m and preventing the separator-rod from twisting or turning on its axis when the separatorbar is lifted out of the sockets, the collar P also serving as a stop-collar as above stated by striking on the lower sleeve of the stand M instead of on the top of said stand, as described in said patent. The foot m through which the bolts m are driven to secure the stand M to the guide-rail E may project horizontally forward below said guide-rail while the sleeves m m are arranged on the back of the stand (see Figs. 1, 2 and 7) or a similar foot m and sleeves m m may both project forward from the body of said stand (see M, Fig. 12), the foot then being arranged on the top of the guide-rail, the last-named construction bringing the separator-rods and separators farther forward and into a position where they will not strike the lower edge of the roller beam in rising, in spinningframes in which the horizontal distance between the back of the ring-rail and the plane of the front face of the roller-beam is very short. The stand, when used near the support S of a spinningframe of the usual construction, is provided with a hanger m preferably cast in one piece with said stand, as shown in Figs. 7 and 12, and from said hanger near the lower end thereof projects a fulcrum stud m secured by any usual means to said hanger.

An anti-friction-roll Q turns on a stud g which projects from a collar q, adjustably held by the set-screw g at the desired height on a separator-rod, and on the fulcrum-stud m turns a lever T, onearm of which is so curved that a tangent to said lever at the point of contact of said lever and the antifriction roll Q will be horizontal at all times, the other arm 75' of said lever carrying asliding weight R which is held by means of a setscrew 1, turning in said weight against said arm 15', at any desired distance from the fulcrum m such distance being so regulated as to allow the weight of the separator-rods and parts supported thereby barely to raise the weighted arm of the lever T, when the free end of the cross-shaft arm descends, the object of the lever T and its weight being, not

to raise the separators but to take a part of the strain off from the cross-shaft, which raises said separators precisely as the ring-rail is raised, that is, by means of the weighted arm f and weight f this being the more necessary because the separator-bar has a less traverse than the ring-rail and it is desirous to make the traverse of the ring-rail as uniform and gradual as possible and to obviate the necessity of increasing the size of the weight f and the power required to raise it.

The stud q is provided with an annular groove g near its free end, into which groove a wire g is laid and bent around said stud, the Wire being of sufficient diameter to project from said groove and to form a collar on said stud and the end-portions of the wire being pinched together, at g to retain the roll Q on said stud. In the same way the leverT is retained on the stud m by a wire m arranged partly in the groove m near the free end of said last-named stud. (See Figs. 1, 9, 13 and 14:.)

The construction above described allows the curved arm of the lever T when placed below the guide-rail to swing withoutstriking the support S of the frame.

Except near the support S, the leverT may be pivoted between the ears m cast on a stand M (Fig. 11), in other respects, like the stand M, shown in Fig. 7 (except that the hanger m shown in said last-named figure is omitted as unnecessary), the curved arm 25 of said lever Tin this case extending over the lower sleeve m, from which said ears m project laterally, and the anti-friction-roll Q being supported by its collar q between the guide-rail E and spindle-rail D and the free end of the stud q sliding in the vertical slot, just as the pin 19' of the collar P is described above as operating in respect to the stand M shown in Fig. 7, said collar P, where the stand M shown in Fig. 11, is used, being arranged above the upper sleeve to of the stand and serving merely as a stop-collar.

The adjustable foot 0 (instead of being formed in two parts, the upper of which is secured on the lower end of the separator-rod and the lower of which is adjustable on said upper part, as in said patent) consists of a single piece and has a collar 0 to receive the lower end of the separator-rod N, a horizontal sole 0 resting upon the roll f during the traverse of said separator-rod, as above-described, and connected to the collar 0 by eX- tensions 0 from said collar. A set-screw 0 turns in said collar 0 and thrusts against the separator-rod N, holding the sole of the foot 0 on a level with or at any desired distance below the end of said rod N, to vary the upper limit of the traverse of the separator-bar and separators.

The separator or separator-blade shown is different in form from what is shown in said patent and is designed to enable the separator to have a greater depth and to secure a more perfect separation of the yarns and therefore to allow of a longer traverse of the ring-rail and a greater speed of the spindles and the use of a lighter traveler.

The shank 2" of each separator I herein described, when in operative position is considerably higher than the middle of the separator instead of being at the same height therewith, the separator not extending above the shank 2" far enough to prevent said separator, when near the upper end of its traverse being thrown into a vertical position against the roller-beam, but far enough to enable the upper part of the separator to rise into the space 1) between the nearest adjacent finger-boards B and between the yarnguides carried by said finger-boards. Below the shank t" the separator reaches down for a distance depending on the length of traverse, the speed of the spindles, the weight of the traveler, and the number of the yarn, because the longer the traverse, the greater the speed of the spindles, the lighter the traveler, or the heavier the yarn, the greater will be the balloon described by the yarn and the greater will be the depth of the separator required below the shank 11' Separators which are drawn or swing backward from between adjacent spindles as the ring-rail rises, must necessarily be of comparatively slight depth, to avoid striking the roller beam or being struck by the rising ringrail and sometimes consistof a plate not over one eighth of an inch in thickness arranged horizontally. I am enabled to use a blade three and a half inches or more in depth, because my separator has a vertical traverse and moves upward out of the way of the ring-rail. Using a separator of great depth, the traverse of the separator may be much less than that of the ring-raihbecause it is only necessary that the separator should move upward far enough to avoid being struck by the rail-ring and downward far enough to prevent the interference of the yarns of adjacent spindles. I can therefore use a much longer traverse of the ring-rail, that is, use much longer bobbins, run the spindles at a greater speed, use lighter trav' elers and spin heavier yarn than would be possible with aseparator of slight depth, it being evident that with a long traverse, or under any of the circumstances above mentioned, which increase the diameter of the balloon, a separator of slight depth would allow the yarns of adjacent spindles to interfere above or below or both above and below the separator.

The shape of the separators I as above described is such that the principal part of their weight, when in a vertical position would obviously be in front of the pivot-pin 7c and would cause them to fall forward. I therefore use aretainer U of sheet-metal, secured to the front of the roller-beam by a screw a which passes through a slot u in the shank of, said retainer near its free end being rounded, at u toward one of the separators on a separator-bar and adapted to press against the sides thereof with considerable friction or to enter slightly one of the slots 01 cut in each separator (to lessen the weight of the separators) and to hold all the separators on said separator-bar in a vertical position.

In some spinning-frames, the horizontal distance from the vertical plane in which the spindles stand to the front of the roller-beam is sufficient to allow separators, shaped as herein shown and described, to be tipped over backward until the center of gravity of the separators is in the rear of their pivot pins and in such cases the retainer U may be dispensed with.
